Question

Sound is just pressure waves in air, and music is an individual taste. Can you place the events in correct order, from the production of a "sound" from an instrument to your listening pleasure?

1. A-minor chord
2. Spiral Organ of Corti moves up and down
3. Basilar membrane resonates
4. Stapes transfers motion to oval window
5. Action potentials are generated
6. Pressure wave moves through perilymph in scala vestibuli of cochlea
7. Alternate waves of air pressure are created
8. Tympanic membrane vibrates
9. Hair cell stereocilia deform and bend
10. Auditory ossicles move and amplify
11. Auditory area of temporal cortex is stimulated
12. Cochlear nerve sends action potentials to brain
13. Auditory meatus funnels air pressure waves
14. Sigh, good tunes

Answer 1

Here is the correct order of events from the production of a “sound” from an instrument to your listening pleasure:

A-minor chord

Alternate waves of air pressure are created

Auditory meatus funnels air pressure waves

Tympanic membrane vibrates

Auditory ossicles move and amplify

Stapes transfers motion to oval window

Pressure wave moves through perilymph in scala vestibuli of cochlea

Basilar membrane resonates

Spiral Organ of Corti moves up and down

Hair cell stereocilia deform and bend

Action potentials are generated

Cochlear nerve sends action potentials to brain

Auditory area of temporal cortex is stimulated

Sigh, good tunes
